Overview

In this project we examined the automatic seagrass coverage estimation of the sea bottom. A total of 12682 images of the seabed at different depths along Croatia’s Adriatic coast were taken with the help of a diving robot. Of these, 6036 images were manually polygon-annotated by hand and made available to the public as pixel maps. Using this dataset, we tested a superpixel classification of seagrass images. To achieve this, we used several different feature extraction methods as for example CNN-Features that turned out to be the best ones in our experiments.

This project is a joint work between University of Zadar - Croatia and University of Applied Sciences Fulda - Germany
